* Ok, third time's the charm. No changes from last time except the CMakeDavid Greene2010-04-021-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | source addition. Apparently the buildbots were wrong about failures. --- Add some switches helpful for debugging: -print-before=<Pass Name> Dump IR before running pass <Pass Name>. -print-before-all Dump IR before running each pass. -print-after-all Dump IR after running each pass. These are helpful when tracking down a miscompilation. It is easy to get IR dumps and do diffs on them, etc. To make this work well, add a new getPrinterPass API to Pass so that each kind of pass (ModulePass, FunctionPass, etc.) can create a Pass suitable for dumping out the kind of object the Pass works on. llvm-svn: 100249

* Let's try this again. Re-apply 100143 including an apparent missingDavid Greene2010-04-021-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | <string> include. For some reason the buildbot choked on this while my builds did not. It's probably due to a difference in system headers. --- Add some switches helpful for debugging: -print-before=<Pass Name> Dump IR before running pass <Pass Name>. -print-before-all Dump IR before running each pass. -print-after-all Dump IR after running each pass.

* Add a form of addPreserved which takes a string argument, to allow passesDan Gohman2009-10-081-12/+12
| | | | | | | | to declare that they preserve other passes without needing to pull in additional header file or library dependencies. Convert MachineFunctionPass and CodeGenLICM to make use of this. llvm-svn: 83555
* stop MachineFunctionPass from claiming that it preserves LoopDependence info,Chris Lattner2009-10-051-2/+0

* Reapply r77654 with a fix: MachineFunctionPass's getAnalysisUsageDan Gohman2009-07-311-0/+52
| | | | | | | | shouldn't do AU.setPreservesCFG(), because even though CodeGen passes don't modify the LLVM IR CFG, they may modify the MachineFunction CFG, and passes like MachineLoop are registered with isCFGOnly set to true. llvm-svn: 77691
